This article compares two approaches side by side to clarify how they differ in principle and practice. Acute ischemic stroke from a large vessel occlusion happens when a clot blocks a major brain artery, cutting off blood flow to a region of brain tissue. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Acute Ischemic Stroke and Intracranial Aneurysm Intervention
Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. Intracranial aneurysms are focal outpouchings of a brain artery wall, and endovascular options aim to seal the aneurysm from circulation to reduce rupture risk.
Coiling vs Flow diversion: Key Differences
Coiling packs the aneurysm sac from within to promote thrombosis, while flow diversion reconstructs the parent vessel across the neck to redirect flow away from the sac. Coiling directly fills the aneurysm and suits many saccular shapes, whereas flow diverters can address wide-neck or otherwise challenging aneurysms. INVAMED offers Spider detachable coils and flow diverter stents to cover both strategies. Which technique fits a given aneurysm is a specialized decision made by the neurointerventionalist.
How INVAMED Supports Both Approaches
INVAMED's neurovascular portfolio spans clot retrieval, aspiration, aneurysm packing, embolization, and the access tools that reach the intracranial circulation. Device sizes, coil diameter ranges, and catheter compatibilities are detailed in product documentation, and buyers should confirm local registration and indication status. INVAMED's neurovascular portfolio includes the KinG stent retriever, Spider detachable and pushable coils, the Libro liquid embolic agent, the Mantis directional and AngioHAND thrombectomy systems, flow diverter stents, and the InWIRE guidewire.
Key Considerations
- Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen.
- Manufacturer statements, including the described up-to-24-hour window for the KinG device, reflect product content and do not establish individual eligibility.
- All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU.
Frequently Asked Questions
What is the Libro embolization agent?
INVAMED's Libro is a non-adhesive liquid embolic agent combining EVOH copolymer, DMSO solvent, and tantalum for radiopacity, offered per INVAMED in multiple viscosity formulas for AVMs and tumors.
What treatment window does INVAMED cite for the KinG device?
According to INVAMED product content, the KinG device is described as capturing and extracting cerebral artery clots within a treatment window of up to 24 hours; eligibility is a clinical determination.
What is the regulatory status of these neurovascular devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Clinical and Technical Context
Speed to reperfusion is a central factor in stroke thrombectomy, which shapes device readiness and workflow in eligible patients. Intracranial aneurysms are focal outpouchings of a brain artery wall, and endovascular options aim to seal the aneurysm from circulation to reduce rupture risk. INVAMED's Libro Non-Adhesive Embolization Agent combines EVOH copolymer, DMSO solvent, and tantalum powder for radiopacity, and per INVAMED is offered in multiple viscosity formulas, including 6 and 8 percent concentrations, for cerebral AVMs and tumors. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. Mechanical thrombectomy removes the clot with a catheter-based device, and it is used in selected patients alongside or after intravenous thrombolysis where indicated. Manufacturer statements, including the described up-to-24-hour window for the KinG device, reflect product content and do not establish individual eligibility. Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion. INVAMED's Spider Intracranial Coil System uses a platinum-tungsten 92/8 percent alloy in detachable and pushable configurations with instant mechanical detachment; according to INVAMED, Spider coils provide aneurysm packing across 2 to 30 mm coil diameters.
